Comment 6 for bug 397892

I can correlate similar behaviour after upgrading from ibex to jaunty to karmic yesterday, screensaver will not initiate on it's own, but will via "gnome-screensaver-command -a" and other gnome applets to lock screen. My occurrence is slightly different that my system will never even try to go into screen saver, rather its as though the system is never seen as "idle". I also have a separate bug report for gnome-power-manager as it exhibits the same problem of never dimming the screen at a set time. There is nothing relevant in xsession-errors, messages, or anywhere I can find.
